Hardening mechanism and plastic deformation behavior in super-hard AlCrNbSiTiN high-entropy nitride nanocomposite coatings
The rapid development of industrial applications places severe demands on the mechanical properties of protective coatings. Unraveling the hardening mechanism and deformation behavior is essential for the design of advanced hard coatings. In this paper, a novel AlCrNbSiTiN high-entropy nitride (HEN) coating with an extremely low wear rate of 6.3 × 10−7 mm3 N−1 m−1 and super-hardness of 46 GPa was deposited. The variation of ion-bombardment energy induces the transformation of the nanocomposite structure and hardening mechanism. The plastic deformation behavior was revealed using Ex situ TEM observation and the MeN-Si3N4 nanocomposite structure is a critical contributor to the outstanding mechanical properties and resistance to deformation.
